Solskjaer has given United players the capacity to show aspects to their game which were nowhere to be seen under Jose Mourinho.

And Herrera has been one of the main benefactors. Under Mourinho he was often overly bullish, one-dimensional, as if reduced to all the core elements of anger, and nothing more.

His performance at the King Power was so much more expedient, more effectual. He moved the ball cleverly through the lines, picked up good defensive positions, made every bursting run across the turf count.

This was not a very good game to watch after a bright 15 minutes from United, with neither team looking like scoring. It is in these passages of play – resembling more of a tactical arm-wrestle than a game of football – where Herrera becomes United’s real hero.
